It's made of carbon fiber, which I assume makes it more visible than
fiberglass would.


Ah yes - the saving grace of the Sparrow Hark. Other glass gliders can
be seen on radar because the conrol pushrods have a significant RCS.
The Sparrow Hawk strategically uses string instead.

Actually, aramid fiber cables for the rudder and ailerons; pushrods for
the elevator and spoilers. The only "string" in it is the yaw string!
